This is encryption and obfuscation on multiple levels, classes passing each others state through hashing and encryption schemes on multiple levels, added bytecode hackery, etc.
Exactly my point – it's unreasonable to expect that higher level of reverse engineering will be done reliably for every release of even a small percentage of the apps being published.
